Didn't want to hijack Paul'* thread with my problem, so I started this one.

Anyway, the left front tire/wheel has been slowly leaking for quite some time. Lately, the leaking has been getting quicker.

But here'* the kicker: I put new tires on in January, and the leak continued as if I didn't do anything.

Is there a connection into the hub to the tire pressure indicator that could leak the air?
And, if so, is it in the hub assembly?

If it is, that'd be great, as I'm replacing the hub assembly this weekend (growling terribly by now), thus should take care of the air leak. *crosses fingers*

no. the tire pressuse light comes on based on calculations in the computer based on wheel speed..

im guessing you have a cracked or leaking valve stem... or possibly some corrosion and pitting on the edge of the rim where the bead sits.. spray some soapy water on the valve stem and wiggle it around a bit... then take the cap off and put some of the solution directly on the valve. if you see no bubbles from these places, try around the area where the rim and the tire meet

I agree with toast. There has to be a defect in the wheel (where tire bead meets wheel), or the valve stem itself is leaking. I assume you had all new valve stems installed with the new tires.

I've got three leakers myself! Will be putting new tires on before winter...it will be interesting to see if I encounter the same problem. I'll have to try that "find the leak with the bubbles" trick....good luck!

when they change the tires make sure they change the valve stems and make a point for them to inspect the bead surface on the rim, if there is any oxydation build up on the wheel, any decent tire shop will clean up the mating surfaces for you for free...

Nice.

Thanks for the replies

Thanks for the info!

Just a follow up on this, had the same problemo r front found a cracked rim. replaced rim and rotated it to r back. Now r front is leaking air.

I have also been plagued with leaking wheels. In the summer months, not one pound escapes. In fall or winter away she goes, the colder it gets the more that leaks out, almost to the point of topping off every 3-4 days and the low tire pressure never seems to code out and beep at me until the tire is down to approx 14-16 lbs. Had valve stems and rims cleaned up last year and for the rest of the winter didn't lose as much air but after awhile started again, this year same old thing. Just both rears, fronts rarely lose much at all. Rear tires are in need of replacement now but the problems have been around since I got the car from used used dealer in 2005

On aluminum rims a good tire shop will make sure bead of rim is clean using scotch brite or fine wire wheel as not damage rim. Then they are supposed use compound that looks like grease and put it on the bead of the rim to help tires seal correctly. I have never had a tire leak or loose air unless those steps were not followed. This also applies to the valve stem too. Lucky here as my cousin does this for a living.
